Fantasy Display Sites ...

Grump, I'm awfully sorry I don't know the answer to your question. I'm going to port you off to the Roundtable for wider viewing and hopefully some kind person there can help!

If you've sold publication rights to your novelette, presumably you don't have the legal right to post it on a display site.

Display sites tend to be about people voting on stories so that they get return votes. It's not really about people looking for new authors. You'd be better off working on other promotions (maybe guest blogging for some people, etc). If you write shorts, getting those published can bring people in (make sure you include your website or blog link in your bio).

A few ideas for you on building a readership:

Start a blog specifically related to the e-novelette. Will it be expanded into a novel someday? Are there related stories that could be told with the same characters or world? Put teasers or promos or other tidbits on the blog.

Print up some postcards or flyers and hand them out or make them available to local writing conventions or the like that are related to the genre of your e-novelette.

Register a facebook or other social media site in a related name and use that.

Post links to the blog or to the manuscript in all of your forum signatures and in your email signatures.

There are plenty of more tactics, but that's a start, I guess. Be proactive and persistent, but also try not to get so caught up in marketing this one book that you don't start writing the next one. Good luck!
